Q:What is the difference between glass tube, sand pipe and glass tube?

The pipeline in the design according to the use of pressure, stiffness and other conditions to determine the need for sand, if the thickness of the pipe can satisfy the pressure requirements and can meet the requirement of stiffness, is generally not the sand.

Q:How is FRP ventilation pipe made?

It should be noted that the flange and the duct shall be a whole and shall be at right angles to the axis of the wind pipe. The flanges of the air duct and its pipe end shall be formed together during the coating process. Glass fibre reinforced plastic pipe flanges shall conform to the provisions of table 5-21.

Q:Mending method for glass fiber reinforced plastic pipe

Other repair methods: choose resin, accelerator, curing agent, high quality glass fiber cloth. Don't let the powder go. It is autumn, the temperature is low, so to put more than summer curing agent, the proportion of the curing agent, accelerator, resin; 1:1.5:8 with glass fiber wrapped around the pipe, coated on the glass fiber cloth for glass steel with a good quick, let the glass steel glass fiber cloth fully soaked, waiting for glass steel fully cured, and then repeated several layers. It will be strong.

Q:Underground garage inorganic glass fiber reinforced plastic wind pipe water out of the way?

As basement ventilation, there are galvanized iron pipes. This kind of iron pipe ventilation pipe, in the steam condensation of weakness will be more obvious - iron sheet wall thin, internal and external temperature difference is more likely to appear.

Q:FRP acceptance standard

Perform hydrostatic test. In order to comprehensively check the installation quality of pipes, the pressure test shall be carried out according to the test methods stipulated in the code for construction and acceptance of water supply and drainage pipe works, and the allowable seepage water quantity shall be carried out according to the standards of the steel pipe.

Q:What are the advantages of FRP pipes?

Light weight, corrosion resistance, aging resistance, long service life,

Q:How to open a DN300 port on the DN600 GRP pipe and install the DN300 gate?!

A 300 hole bonding a short tube, in the installation of a valve (see what install valves, iron needs a steel plastic conversion, direct bonding glass steel flange, a glass tube) special glue (a few years ago had forgotten what, like what's called 507), this thing is good to buy special glass steel where there is, the effect is quite good

Q:Which is better, PVC pipe and GRP pipe?!

To see the composition of your gas, fiberglass can be chosen according to the requirements of different resins for corrosion protection, and PVC for some gases are not corrosion-resistant,

Q:What kind of epoxy resin and formula do you need for making fiberglass pipe?

By explaining the materials, tools, moulds, renovation and repair, process, structure and various products, the latest development direction, process technology and application of FRP products are described.

Q:What are the advantages of glass fiber reinforced plastic sand pipe than HDPE pipe?

Advantages of HDPE tubes:1. It is easy to form the closed anti-seepage system by butt welding and electrofusion welding. When laying along the trench, the excavation of the trench can be reduced and the amount of the fittings can be reduced.2 、 light weight and easy to install;3 、 strong abrasion resistance and excellent hydraulic performance, the buried pipeline can be protected without outer layer. The utility model can be applied to the earthquake and the soil subsidence area of the mining area, and can be laid on the bottom of the river by immersion method.4 、 chemical resistance, resistance to internal, external and microbiological corrosion, corrosion resistance, and health. The utility model is suitable for conveying acid and alkaline substances, conveying sewage, natural gas, gas and other substances;5, good environmental adaptability and frost resistance. It can be used in indoor and outdoor water supply pipelines.6, long service life, with more than almost 50 years of service life;7, easy to recycle
